Postgraduates’ communal motivations for mentoring undergraduate researchers^a

		Motivations
Vocational	Scientific community development: Anticipation that mentoring will benefit the scientific community	Your mentor–mentee relationships is very, very important for science. It’s something that helped me along the way a lot of times, professionally growing up. I had good mentors and I wanted to be a good mentor to the next generation of scientists there.—Aiden
	Social norms: Perception that mentoring is a common or expected activity of their position	Before I was here, I was in the UK at [university], and [mentoring is] something we always did … it’s good training also for postdocs and PhD students.—Grace
Psychosocial	Altruism: Desire to serve others through mentoring	I feel like I learn a lot in training other people… I get a lot back out of it. You feel valuable to other people, and it feels… like a valuable use of my time… I’m making a big difference in someone else’s life, and I like that.—Samantha
